l Dial tone is transmitted to the subscriber until the first digit is
dialed or timeout occurs.
In addition to transmitting dial tone to the originating subscriber,
the system checks the subscriber’s class of service. Data base
class-of-service tables (resident in system CPU RAM) define
to the system exactly what features are assigned to the
originator’s lineReception of34.2.8 The subscriber recognizes dial tone as a signal to begin

l During a digit store routine, the CPU stores each digit in a
scratch pad area of the CPU memory. The digits are stored in
the digit store scratch pad only long enough for the CPU to
identify the station being called (dialed). Then, this information
is transferred to call store for the duration of the call. (The
word format for digit stores and call stores is described in TL-
130200-l 001.)

SW 521034.2.10 After the CPU has received all the dialed digits, it will
determine who is being called or how the call is to be routed. It
also checks the subscriber’s class of service (line record code
data base tables) to determine if the subscriber is allowed to
make the kind of call dialed. If the call is allowed, for instance
station-to-station, the CPU determines whether or not the
called telephone is busy, sends a 
ringback (or busy) signal tone
to the originating subscriber,...

34.9, the two parties can talk to each other, and the two time slots
are in a stable call condition. The time switch (under control of
the 
INCKS card) cycles through a regular scanning routine and
looks at all of the system time slots, one at a time. During each
look. four tasks are executed:

TL-130500-1001Netlink35.5 The NETLINK is the software component that provides
intercomponent communications across the packet transport
system and central packet link. It resides, in various forms, on
the APM, SPM, 
UCWDCP, NIC and ADMP cards. NETLINKconsists of three layers:
0 Layer 1 (Physical Layer). This layer provides the software
interface with the packet line interfaces and the packet
transport system hardware.
0 Layer 2 (Mini-Packet Protocol Layer). This layer implements
the link layer protocol....
